Magna-Robot

In this activity children will determine from which type of material the robot should be made and will learn that some metals are magnetic.

Description

A robotic caterpillar has been designed which can crawl across the surface of the heart to deliver treatment. The tiny robot, just a few centimetres long, can move at up to 18 centimetres per minute, controlled by a joystick from outside the body. Doctors follow the robot's movement on the heart's surface using a magnetic tracker on the skin.

Children will determine from which type of material the robot should be made. They will learn that some metals are magnetic. They will classify a range of materials, including metals as magnetic or non-magnetic and explain how their work enabled them to do this. They will describe and explain how magnets can be used.  

Learning Objective:

-    that some metals are magnetic but most materials are not

Children will learn:

-    to carry out an experiment to test a prediction

-    to apply scientific knowledge to everyday situations
